If the poster was Australian and you wanted a bite.... just ask him about the Rugby, Netball and oh dear, the Ashes! (all those sporting egos and icons; finally the world can see Australia for what it really is.......the GAFA)
"Septic Tank" = Yank, often shortened by our antipodean cousins to "Sepo's"
Speaking of which......Im "Hank Marvin" (f@ckin starvin)....time for supper!
PS: GAFA for you Sepos is "Great Australian F@ck All"
